Every game it turns Riflemen from the best starting infantry to T-800's walking around at the beginning of Terminator 2. Fearless, emotionless, killing machines. At 3CP. So by the time you're finally getting your first tech down to help slow down the Doom Blob guess what? Your Volksgrenadiers/Sturms can't compete unless your opponent is a total moron. Maybe if they're high vet and green cover. STGs are kind of overrated and irrelevant at that range.
MG34? Smoke, ez. Flaktruck? LOL. Luchs, ohai Stuart. It wasn't as prominent because it was confined to the Priest commander but now that Mr. Calliope is out, your infantry extermination skills equal or surpass that of Veteran Obersoldaten. Now it is on a virtually flawless, infantry exterminating commander. At 3 CP. Not only that you have no early vehicles to fear that early on that present such a threat as opposed to say a Stuart, T-70, AEC etc. Not that it matters anyway because your stuff is better BUT the fact still remains of being extremely effective AND efficient. Versatile shouldn't mean exceptional at everything.
When 7 Pop Riflemen fearlessly walk up to Vetted Obersoldaten I have to protest this. You don't even have to wait a minute to equip them nor research them. It's just HAHAHAHA WHO NEEDS COVER?!?! It's not like USF has to spend a ton of munitions to make their infantry viable in combat. It's just at that range, on a basic infantry unit that has that many abilities already, so early, no just no. Single? Fair enough. Double? Would you allow Obers to equip two MG34s?
(And "BUT THEY'RE 70 MUNS A PIECE!" Worth every bit of it. It's not like they ever drop them like say a PTRS Rifle.)
